GLASS He. seems. Specification of Application filed August 23 To allwhom it may concern:

Be it known that l, WiLLmM MiLLs'rEiN, a citizen of the United States ofing at Beaver, in the county of Beaver and State of Pennsylvania, haveinventedcertein new and useful improvements in Glass- Molds, of whichthe following is o specificstion, reference being had therein to theaccom mnying drawing.

'inis invention relates to molds for forming glass and plastic meted,and more particularly for deep figured or ornamental were and ressblanks.

fhe primary object oi: this invention is to f roviden mold consisting ofreadily separeole sections, drawing direct from the center, which willshape the were and ornament its base and upper edge.

Further objects of this invention are to a breakage of were; a reductionin the amount oi-iron used in a mold; dispensix'ig with keying "andpinning of molds, requires less cutting of amolded article, and numeroneother advantages which will hereinafter A still iur r object is, toprovide. the andv guide-pins to insure a ready opening and closing ofthe mold.

The construction. of the improvement will be fully describedhereinafter, in connection with the accompanying drawing which forms itdart of this specification, and its novel ice; tures will be defined inthe appended claims.

in the drawing: Figure 1 is a side elevetion of u mold embodying theinvention, l ig. oi the some, l ig. Ii 21, control vertical section ofthe mold, with the plunger in position. thereon, Fig. is a per spectiveview of one section oi the body of the mold, Fig. 5 is a, detailperspective view of a part of the base of the mold, Fig detailperspective of a section of the i manuiocturing the edge of the eperspective view oi one ol' arms which secure the sections of the moldbody together, and Fig. 8 is plan oi 1i mold in. open position.

The reference numeral 1 designates the were, l

base of the mold provided with u central upwardly projecting circulardisk 2 having its periphery be eled downwardly, and surmounted by a.l)()SS 3, the periphery of which is beveled upwardly. The upper surfacei of the boss 8 is serrated to impart-ornamental Letters Patent.

serrations to the bottom of illustrated in Fig. 3.

The base i formed on its upper surface with a plurality of radialgrooves 6 to receive guide arms 7, each of which is pivotully sc curedat its inner end to one of the sections 8 oi the body of the mold, andcarries at its outer end a roller 9.

Each of the mold its upper receiving said. ring width on its undersurl'uc'c usui 13 to serrate the edge of the were. This ring; i2 is alsooi undulating contour as shown at Ll to scallop the edge of the disk, aswell as to import ornamentul serrations thereto. The sections 8constituting the body of the mold are each formed with a. lunizonlulgroove 15 to reccive pins 16 projecting 'l'rom the inner concave facesol' the clamping arms 11'', said arms being pivotally secured togetherby overlapping performed lugs 18, and pP-JUC pins 19 m l the manner wellknown in the art. Handles l l the were 5 us sections (l is provided atedge with a socket l0, said socket pins ll depending lrom u rm;: 1;,

v 20 and '21 are connectml to two oi'the clemping arms, and a thirdhandle '4 is secured to a. shaft 23, carrying a locking eccentric whichlocks the mold sections together The utility and opere/iioi'i oi theinvention will be readily understood. Air or the molten glass is)OLl1C(l into the .nuld lllc plunger 24 is forced down to form the wereThe dow nword. pressure of the plunger compresses the bottom of the diskogui isi the boss 4, thus indenting the 'under surlace oi the wereillustrated in Fig. 3. The. plnngrr is provided with an annular dingoli'wliioh nears upon the ring; 12 to impart the rnipiired ornamentalconlm'metion lo the edge of the were. The clamping arms .17 have u l'reel sliding movement upon the mold sections 8 by means of the grooves 355and pins 16 permitting the molded disu to lj easily und quickly removedfrom the mold the 1'Oll(.l:- 9 and pivoted arms 7 coiiperutingv in theopenin g of the mold.

l desire to call attention. to the fact tlurt when the mold is opcn,thepivoted parts will prevent a figure irom sticking to the mold, and usthe pivoted parts of it mold release the piece of were, the ligurcd orornume'ntal part oi the were is prevented from being; injured. Havingnow described my iii, cnlion what I claim as new, is:--

, 1. in a glass mold, the cemhinetion with e.

)Glllg, scrrutod i'or a portion ol' its and provided with means engagingin said base, formed with radial grooves onits upper l pivotally securedtogether and embracing 25 surface, of mold sections each having a guide1 arm pivotally secured thereto, and fitting the grooves in said base,and also 'lormed with a horizontal groove, and a plurality of clampingarms embracing saidmold sections horizontal grooves whereby said armshave i free sliding movement upon said sections 2. In a glass mold, thecombination with a base provided with a central serrated boss, and aplurality of radial grooves, of mold sections, each having a guide armpivotally' secured thereto and fitting said grooves, rollers carried bysaid guide arms, clamping arms pivotallf secured together and embracingsaid mo d sections, and means for ornamenting the upper edge of themolded article.

3. In a glass mold, the combination with a base provided with a centralserrated boss, and a plurality of radial grooves, of mold sections, eachhaving a guide arm pivotally se cured thereto and fitting said grooves,rollers carried by said guide arms, clamping arms said mold sections,and means for ornamenting the ed e of the molded article, comprising arin,g i'ormed with bands or undulations, and serrated on its undersurface.
